Gerbera plant named ‘Kings Canyon’

ABSTRACT

A new and distinct cultivar of  Gerbera  plant named ‘Kings Canyon’, characterized by its compact, upright and uniformly mounding plant habit; freely flowering habit; bright yellow-colored ray florets; yellow-colored disc florets with orange-colored apices; and upright, strong and relatively short scapes.

Botanical designation: Gerbera jamesonii.

Cultivar denomination: ‘KINGS CANYON’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Gerbera plant, botanically known as Gerbera jamesonii and hereinafter referred to by the name ‘Kings Canyon’.

The new Gerbera plant is a product of a planned breeding program conducted by the Inventor in De Kwakel, The Netherlands. The objective of the breeding program is to create new compact container Gerbera cultivars with numerous inflorescences, good garden performance and attractive inflorescence coloration.

The new Gerbera plant originated from a cross-pollination during the summer of 2005 in De Kwakel, The Netherlands of Gerbera jamesonii ‘Flocave’, disclosed in U.S. Plant Pat. No. 21,339, as the female, or seed, parent with a proprietary selection of Gerbera jamesonii identified as code number I 07 304, not patented, as the male, or pollen, parent. The new Gerbera plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in De Kwakel, The Netherlands during the spring of 2006.

Asexual reproduction of the new Gerbera plant by tissue culture in a controlled environment in De Kwakel, The Netherlands since the summer of 2006 has shown that the unique features of this new Gerbera plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Gerbera have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Kings Canyon’. These characteristics in combination distinguish ‘Kings Canyon’ as a new and distinct cultivar of Gerbera:

-   -   1. Compact, upright and uniformly mounding plant habit.     -   2. Freely flowering habit.     -   3. Bright yellow-colored ray florets.     -   4. Yellow-colored disc florets with orange-colored apices.     -   5. Upright, strong and relatively short scapes.

Plants of the new Gerbera differ from plants of the female parent, ‘Flocave’, in the following characteristics:

-   -   1. Plants of the new Gerbera have more uniform inflorescences         than plants of ‘Flocave’.     -   2. Inflorescences of plants of the new Gerbera have more         numerous inner ray florets than inflorescences of plants of         ‘Flocave’.     -   3. Ray florets of plants of the new Gerbera are bright yellow in         color whereas ray florets of plants of ‘Flocave’ are white in         color.

Plants of the new Gerbera differ from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Gerbera are more compact than plants of the         male parent selection.     -   2. Plants of the new Gerbera have shorter scapes than plants of         the male parent selection.     -   3. Plants of the new Gerbera and the male parent selection         differ in ray floret coloration.

Plants of the new Gerbera can be compared to plants of the Gerbera jamesonii ‘Flostone’, disclosed in U.S. Plant patent application Ser. No. 12/454,020. Plants of the new Gerbera differ from plants of ‘Flostone’ in the following characteristics:

-   -   1. Leaves of plants of the new Gerbera have more rounded apices         than leaves of plants of ‘Flostone’.     -   2. Plants of the new Gerbera have larger inflorescences than         plants of ‘Flostone’.     -   3. Plants of the new Gerbera have longer scapes than plants of         ‘Flostone’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Gerbera plant. The photograph shows the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Gerbera plant. The photograph comprises a side perspective view of a typical flowering plant of ‘Kings Canyon’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown in a glass-covered greenhouse during the spring and summer in De Kwakel, The Netherlands and under conditions and practices which approximate those generally used in commercial container Gerbera production. During the production of the plants, day temperatures ranged from 19° C. to 26° C. and night temperatures ranged from 16° C. to 18° C. Rooted young tissue-cultured plants were planted in 19-cm containers and were six months old when the photograph was taken and ten months old when the description was taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, Fifth Edition, 2007, except where general terms of ordinary dictionary significance are used.
